Discogs is free. Why pay for What I Already Own?

If you only collect records and market value is all you need, Discogs is an excellent choice. What I Already Own is worth paying for what Discogs doesn't do: your books in the same collection, a scan that answers without a signal, and what each discography is missing.

Does What I Already Own use Discogs data?

Yes, in part: every month Discogs publishes a data dump of its database under a CC0 license, which we combine with MusicBrainz. We do not use the Discogs API.

Yes, nothing stops you: Discogs for market value and buying, What I Already Own for the inventory of your records and books, even without a signal.

Can I import my Discogs collection?

Not yet: What I Already Own does not import files. Discogs exports your collection as a CSV, so keep it; here, you rescan your records, a few seconds each.

Which app tells me what my vinyl is worth?

Discogs: low, median and high value for your collection, based on sales on its marketplace. What I Already Own does not show a market value today.

What I Already Own

What Discogs does better

It's free. Collection, apps and wantlist cost nothing.¹²
Market value. Discogs estimates what your collection is worth from actual sales on its marketplace; What I Already Own does not show a market value today.¹
Buying what you're missing. The Wantlist leads straight to sellers of the record you're after.⁷
Pressing detail. The Discogs database, written by its members, tells apart every edition of the same album.⁶

How What I Already Own is different

Books too. Records and books in a single collection, with the same scan.
An answer without a signal. At a flea market, digging through a crate, the scan tells you whether the record is already on your shelf, even with no connection.
What each discography is missing. The app counts the studio albums you have and lists the ones you don't.
An app without an app store. It installs from the browser on iPhone and Android, and works the same on both.
